A typical home projector (250 W) costs C$0.051 per hour, or about C$3.07 per month at 2 hours a day in Nova Scotia. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |

How to lower the cost of running a home projector
- Use eco lamp mode. It cuts power by 20 to 30 percent and extends lamp life.
- Watch in a dark room so you can run lower brightness.
- Unplug it between uses. Some models keep fans running in standby.
In standby it draws about 1 W, which adds roughly 9 kWh (C$1.79) per year if it is never unplugged.
